.NET PDF Optimization SDK
Compress any document to PDF using unrivaled optimization techniques.
The GdPicture.NET PDF Reducer SDK is probably the most complete PDF optimization engine of the market. More than 10 years of continuous research have been required to address all areas of compression and optimization, with a focus on font optimization, data compression, and image analysis.
PDF Optimization is about serializing several compression algorithms to surpass the limitations of some compression schemes while removing unwanted or unused objects and applying several other techniques when necessary.
On this page you will find several categories of optimization, each containing different functionalities, which can be enabled or disabled depending on the document and context.
In a PDF file, many objects can be redundant, unwanted, or unused, and therefore, be removed. This includes:
Control image compression
Advanced image compression
GdPicture.NET includes many hyper-compression features, check our pages for more information:
Fonts used to render the document content are an essential part of the document structure of a PDF, since its main goal is to accurately display your document regardless of software, hardware, or the operating system. Embedded fonts which are becoming mandatory in new PDF Standards are optimized using several techniques:

Other quality enhancement features
PDF optimization also means insuring the quality of a document for optimum reading, without slowing the loading process even on large files.
Areas of use
PDF Optimization is dependent of the context and purpose of documents. Every organization has different contexts to manage, sometimes required by the industry, sometimes by law, or simply by internal usage.
The PDF Optimization SDK allows you to address all contexts by enabling/disabling the features you need.
Below you will find a few examples where PDF optimization needs to be adapted:
Electronic document exchange
Documents must be fast to load, so anything slowing viewing and sharing should be avoided. Small and linearized PDF documents are favored to reduce response times.
Archiving often requires maximum compression of the files to save space. However, if a sufficient resolution is needed to keep a good quality document, redundant or unnecessary content is usually removed.
Printing requires to keep a high resolution for a correct reproduction, colors and transparency need to be preserved.

Do you want to know more about PDF optimization?
We have created an article about issues, constraints, and methods for optimizing PDF files.
The text is based on a presentation held at the PDF Day – France in April 2018.
Organized by the PDF Association, the PDF days are the meeting place of the PDF industry, where experts conduct educational (non-commercial) presentations, panel and discussion-based sessions about the format.
